  2. (a) Body mass index (BMI) categories for children according to Cole et al.
  3. (b) Family group based on parental BMI; High: 2 parents with BMI ≥25 or 1 parent with BMI ≥30 and low: both parents with BMI ≤ 25
  4. (c) Weight status according to BMI categories as following; normal weight 18.5–24.9, overweight 25.0–29.9 and obesity > 30
  5. (d) Family education definition: Low: neither parents have an academic education High: at least 1 parent have academic education
